Lisp for moving blocks

Hi all,

I often view this forum for hints and tips but have a question I can't find an answer to so I've taken the plunge and decided to join.

I'm trying to create a function that will: 1) Select a named block and move it to a new co-ordinate, then 2) insert a new block at a pre-specified point.

Basically it's so I can add a new block to a drawing frame and one of the existing blocks within it moves to accommodate it. (if that makes sense).

I've dabbled with lisp routines and using the tool pallets in the past but never for this kind of thing. How should I go about it?

Cheers.

Edit: It's to be used in AutoCAD 2007/8.

Think about how you might approach it in 'pseudo-code':

• Prompt user for selection of block(s) to move (ssget or entsel)
  
• Prompt user for selection of new block file to insert (block name hard coded into program?) (getfiled)
  
• Prompt user for insertion for new block (again, should this be hard coded into the program? - will it be the same every time?)
  
• Insert new block if possible (command "_.-insert" or vla-insertblock or entmake).

You might have to go back a few stages here as I really am a begiinner at this. Whats 'pseudo-code'?

Whats 'pseudo-code'?

Code that maps out the intention of the program without any syntax etc.
